Title: Metallic catalyst carrier
Inventor: ITO KEIJI
IPC: F01N13/02
Filed: 1992-04-24
Abstract: PURPOSE:To provide a metallic catalyst carrier having practically elliptic cross section free from the generation of damage by thermal stress. CONSTITUTION:A honeycomb cylindrical body 3 having practically elliptic cross section and on which many air flow passages S are formed is made by laminating alternately a metallic flat plate 1 and a metallic corrugated plate 2 while winding. The joining ratio of the flat plate 1 with the corrugated plate 2 at major axis parts 3a, 3b is regulated to be larger than the joining ratio at a minor axis part 3c. The honeycomb cylindrical body is joined with a cylindrical housing 4 only at arc-shaped outer circumferential surfaces 3d, 3e. The catalyst carrier expands in the minor axial direction and shrinks in the major axial direction in the case of high temp. The honeycomb cylindrical body 3 has relatively large rigidity at the major axis parts 3a, 3b and, on the other hand, freely deforms at the minor part 3c because of its relatively small rigidity. Even if the housing 4 expands and deforms in the minor axial direction, as the honeycomb cylindrical body 3 is not joined at this part, it is not forcedly deformed. As a result, the damage at the joining part of the flat plate 1 with the corrugated plate 2 is prevented.

Title: Polypropylene laminated paper for insulation
Inventor: KUBO HIROSHI
IPC: B32B27/10
Filed: 1977-11-04
Abstract: PURPOSE: To prevent swelling by insulating oil and also to reduce the increase of thickness by giving uneven surface to polypropylene-laminated paper comprising a fiber paper and a polypropylene film layer.  
     CONSTITUTION: An electrically insulated laminate paper is obtained by integrally adhering a polypropylene film whose surface is provided with an uneven surface by an embossing processing with a fiber paper (e.g., a low density kraft paper. The uneven form is made so as to be given on the surface of polypropylene film which is on the side of no contact with the fiber paper, by a method in which the adhesion of both fiber paper and polypropylene film is made with an uneven-surfaced roll, for example. Since this laminate paper is greatly reduced its thickness by the early drying process, the final augumentation of thickness due to the swelling of insulating oil is remarkably small even if the thickness is increased by swelling by insulating oil. Thus, it is possible to keep the passing of insulating oil better and also to prevent the occurrence of wrinkles.

Abstract: PURPOSE:To prevent the remarkable decrease of performance of a thermoelectric effect element due to heat transfer caused by convection and radiation of air flowing through a space between thin plates from the side of a thin plate having exothermic action to the side of a thin plate having endothermic action, by filling foaming thermal insulation material in the space between the two thin plates. CONSTITUTION:Foaming thermal insulation material 7 like rigid urethane foam and phenol foam is filled between two thin plates 2. In order to obain excellent filling property in a thin gap, reactivity of the above thermal insulation material 7 has a gel time of about 90 seconds which is slower than the general-purpose material for a refrigerator and the like by a little less than 30 seconds. Its thermal conductivity has thermal insulation property of about 0.0140 (Kcal/mhr  deg.C). By filling the foaming thermal insulation material in the space between the two thin plates 2 of the thermoelectric effect element 1, the transferring quantity of heat from the side of the thin plate 2 having exothermic action to the side of the thin plate 2 having endothermic action can be remarkably reduced. By using the forming thermal insulation material 7 of the lower thermal conductivity, the performance of the thermoelectric effect element is the more improved.
